Tempsens Instruments IPO: Final Listing Result

Tempsens Instruments delivered one of the strongest mainboard IPO debuts of 2026, listing well above even the most bullish grey market estimates from the run-up to the issue.

Shares opened at Rs. 634 on the NSE, a gain of 111.33% over the Rs. 300 issue price, and at Rs. 631.20 on the BSE, up 110.40%. The final grey market premium of roughly Rs. 300 to Rs. 317 ahead of listing had already pointed to a strong debut, but the actual listing gain came in slightly above that range, confirming the demand seen throughout the subscription window carried through to listing day itself.

Financial Snapshot

Tempsens Instruments has posted consistent growth across the last three fiscal years, a key factor behind both the strong subscription and the listing-day performance.

Revenue from operations grew to Rs. 444.88 crore in FY26, up 17.53% from Rs. 378.53 crore in FY25 and Rs. 274.81 crore in FY24. Profit after tax rose to Rs. 71.07 crore in FY26, up from Rs. 62.56 crore in FY25 and Rs. 40.92 crore in FY24, a increase of roughly 13.6% year-on-year. EBITDA stood at Rs. 113.17 crore, translating to a margin of approximately 24.8%, and the company’s return on capital employed stands at 21.6%.

Valuation and Risks

At the Rs. 300 upper price band, Tempsens Instruments was valued at around 35 times its FY26 earnings, with an EV/EBITDA multiple of roughly 22.66 times, implying a market capitalisation of about Rs. 2,515 crore at the issue price, a figure that has since risen sharply given the listing-day gain.

The company’s revenue concentration is worth noting, metal and petrochemical industries together contributed about 41.13% of FY26 operating revenue, tying its fortunes partly to cyclical industrial demand. India’s temperature sensor market was valued at roughly Rs. 18.8 billion in FY26 and is projected to grow to Rs. 28.8 billion by FY31, an 8.9% compound annual growth rate that supports the company’s long-term growth story, though past listing-day enthusiasm is not a guarantee of how the Tempsens Instruments stock performs from here.
